And when I turn the ceiling light on in the bedroom with the switch that
is 3 feet away, there is a pause in the sound. It's silent for a second
or so. But the picture isn't affected. There isn't even a blink.

And if I turn the light on in the stairway, which is 20 feet away, I get
the same effect. If I turn either light off, I sometimes get the same
effect and other times, maybe not.

If it do it several times in a row, after the first, second, or maybe
the third time, it stops happening.

When I last asked about this on sci.electronics.repair and maybe here,
no one had any good ideas. IIRC the most common suggestion was that I
was wrong and it wasn't happpening.

But here it is 3 years later, and I don't notice it as often I think
because I'm used to it, but it happened yesterday, while I was 20 feet
away (normally I'm not paying attention when I'm that far away, and I
wasn't but I noticed anyhow.)

A lot of strange things, and little things that I can see no reason God
would do, since they don't promote anything he wants, not even belief in
him.

Could be a noise spike that the unit picks up and reacts to, perhaps
tripping an audio limiting circuit temporarily so that you don't hear a
gigantic pop.

Does the unit have a remote? Does the behavior still occur when you put
black tape over the IR "eye"? Are these LED, CFL or incandescent lights?

Yes remote but never tried tape. Using the actual remote never causes
a loss of sound. Why would the light from the fixture do that, even if
it includes some IR? And what about the light from the stairwell (and
the upstairs hall on the same switch). I don't t hink either of those
lights can reach the IR eye.


They used to be incandescent and now they are CFL. Same thing either
way. Until yesterday I had 60 or 75W equivalents in the ceiling
fixture. Isn't that 15 or 19 watts? times 3. It wasn't enough to
read with so yesterday I put in 100w eqivalent, 25 watts times 3.


I think the spark from the on off switch, a silent switch with no or
almost no detent, is causing radiation that does soemthing.


If I remember, I'll do some more tests.
